SYSTEM FOR PRODUCTION OF ETHANOL AND CO-PRODUCTS WITH RAW STARCH HYDROLYSIS AND SOLVENT WASHING OF FERMENTATION PRODUCT

摘要

A system for the production of ethanol and co-products is provided. The system facilitates an overall reduction in the use of energy, for example, by reducing the mass of wet solids supplied to a distillation system. The system also reduces the amount of energy used to dry the wet solids component of a fermentation product, for example, by increasing the ethanol concentration of the wet solids. The system also facilitates the recovery of co-products including bioproducts and other biochemicals extracted from components of the fermentation product. The solids component of the fermentation product may be dried and constituted into a meal that may be used for animal feed, among other uses.
